Nikon 8mm f/8 Fish-eye-NIKKOR Non-AI Nippon Kogaku Japan Manual Focus Lens {Built-In Filters: L1A, Y48, Y52, O57, R60}

Nikon 8mm f/8 Fish-eye-NIKKOR: full-frame 180-degree circular fisheye from Nippon Kogaku.

This is one of the most extreme optics Nikon ever put the NIKKOR name on. At 8mm with a 180-degree angle of view, it renders the full frame as a circular image, pulling in everything in front of it in a way no rectilinear wide-angle can touch. The fixed f/8 aperture keeps the design compact and the image circle consistent, and the built-in filter turret, carrying L1A, Y48, Y52, O57, and R60 filters, means you have contrast and tonal control without needing to thread anything onto the front.

Manufactured by Nippon Kogaku Japan, this is a Non-AI F-mount lens, meaning it predates Nikon's Aperture Indexing coupling system. On modern Nikon bodies, that requires stopping down to meter or using stop-down metering manually. Film-era Nikon F, F2, and compatible bodies use it natively. The manual focus operation is straightforward given the depth of field at 8mm covers almost everything from close distances to infinity.

Lenses like this don't appear often. The combination of Nippon Kogaku manufacture, the integrated filter wheel, and the true 180-degree full-frame fisheye projection makes it a collector's piece that also still functions as a working optical tool.

Who It's For

Film photographers shooting on Nikon F or F2 bodies get the full native experience, with the built-in filter turret offering on-the-fly tonal shifts that matter on black-and-white film. Architectural and environmental photographers who want circular fisheye projection across the full 35mm frame will find the 180-degree angle of view does things no standard ultra-wide can replicate. Camera collectors drawn to Nippon Kogaku Japan optics will recognize this as a historically significant piece of the F-mount lineage. Digital shooters with stop-down metering capability on modern Nikon bodies can still put it to work.

FAQ

What does Non-AI mean, and how does it affect use on modern Nikon cameras?

Non-AI means this lens predates Nikon's Aperture Indexing coupling system. On modern Nikon bodies, you'll need to use stop-down metering or manual exposure mode. On film-era Nikon F, F2, and compatible bodies, it works natively without modification.

Does this lens produce a circular or full-frame image?

It produces a circular image filling the full frame. The 8mm focal length and 180-degree angle of view create that distinctive circular projection.

What are the built-in filters for?

The integrated filter turret carries L1A, Y48, Y52, O57, and R60 filters for contrast and tonal control. You rotate them into place without needing to thread anything onto the front element.

What's the depth of field like at f/8?

At 8mm, depth of field is extremely generous. Essentially everything from close focus distances to infinity falls within acceptable sharpness, making manual focus straightforward despite the lack of autofocus.

Is this lens manufactured by Nikon or a third party?

This lens is manufactured by Nippon Kogaku Japan, the original entity behind the Nikon brand. It carries the NIKKOR name as a genuine Nikon optic.

Can you use this on digital Nikon cameras?

Yes, but with limitations. Non-AI lenses require stop-down metering on digital bodies; they won't couple with the camera's automatic metering system. Manual exposure mode works without restriction.
